CI-IIMNEY CAP.

Application filed January 141-, 1928. Serial No. 246,771.

This invention relates to chimney caps or cowls, and has lor its primaryobject to provide a coioperatively siu'iple and inexpensive device oilthis character' adapted to lform a i partial closure for the top ol thechimney, and thereby prevent wind, rain, snow and other foreign n'lattertrom passing down the ch i uiuey.

A lurther obj ect is to provide an improved i hood lor the cap, andsimple and ellicient mountin,o` means lor the hood, whereby the lattermay be readily removed lor renewal or repair.

A still lui-ther object is to provide a chimney cap embodying aiiiinimuin number ot uielrllic parts capable of corrodingn or4detiufioratinn from longr exposure to the elements, and including` amolded concrete supporting;` base lor the hood adapted to be secured bymortar ou the top ol. the chimney proper to term a finishing` block forthe latter.

ilnother object is to provide the supporting base with removable hoodsupporting posts or upright rods, so that the latter may be liriulyattached, although readily detachable 'lor renewal.

Still another object is to generally improve this class of devices so asto increase their utility, durability and eliiciency, as well as tominimize' the cost of manufacture.

The invention consists in the novel il'orm, combination and arrangementof parts hereinatter more fully described, shown in the accompanying'drawings and claimed.

ln the drawings Vligure l is an elevational view of a chimney capconstructed. in accordance with the present invention and mounted on thetop oi a chimney.

l0 Figure 2 is a top plan view thereof, partly broken away and insection.

Figure 3 is a vertical section on of Figure l. y

Figure l is a view similar to Figure 3, showing a modification of theinvention.

Figure 5 is a horizontal section showing` a further modification, and

Figure G is a fragmentary transverse vertical section on line (5M-G oi'Figure 5.

Referring more in detail to the drawings, the inwntion is illustrated inconnected with a chimney proper 5 ot ordinary brick construction, andincludes a supporting' base 6 consistingoi" a hollow molded concreteblock adapted to be secured by mortar on top of the chinmei/'f' properto form a linishing block for line 3 3 the latter. This base block (l isoil slightly larger size at the bottom than the upper end oil thechimney so as to overhang the sides oi the latter, tl e sides of theblock all .inclining ce or sloping outwardly and downwardly to shed rainand the like outwardly of the sides ol' the upper end el the chimney andpreserve the adjacent bricks and mortar from moisture.

The central ve tical passano or opening1 7 G5 .in the base blocl: isregistered with and 'forms a continuation of the smoke inissag'e or llueot the chimney, and completely embedded in the base block at the ilfourcorners oit the latter are nuts or nut members 8 into which are 70removably threaded the lower ends of hood sifipiwitiup` posts or uprightrods 9.

'lhe lower en ds ol. the rods S) are removably .fitted in vertical.openings `formed in the base bloclr G in alinement with. and above thethreaded bores of the nut members 8, so that the lower terminals of saidrods may be enraged with or disengaged `from the base block as well asthe nut members :for ready renewal.

A hood or hood plate l0 is removably mounted on the upper ends of theposts 0r rods 9 so as to be supported in spaced relation to and abovethe base block G to permit the escape of the smoke and products oilcombustion, while preventing` down-drafts and a5 entrance of rain, snowand the like directly downward. into the chimney. The removability ofthe hood permits of its ready rencwal, and said hood is preferablyformed of an elongated rectangular sheet oil metal having an. upwardlyarched intermediate port-ion ll and inclined. ends l2 to readily shedrain and the like. The hood plate is a greater area than that oli thebase block so as to project outwardly ot the sides ol. the latter andolfectively exclude the rain and the like from the interior of thechimney and shed the same outwardly of the sides o'f the latter.

rlhe upper ends oit thc posts 9 pass through openings in the hood plate10 at the juncture of the inclined. ends 19. with the arched portion 1l,and in the 'forms oil the invention shown in Figures 1 and 3 the hood isclamped between pairs el' nuts 13 removably and adjustably threaded onthe upper ends of the posts 9.

In the form of the invention shown in Figure a, metallic spacing andJroteetin,ef sleeves 14 are placed on the posts 9 with their lower endsresting on the top of the base block (l, while the hood is removablyclamped down against the upper ends of the sleeves la by fill nuts 15applied to the projecting upper ends of the posts 9. In the form of theinvention shown in Figure 5, the nut members 8 are integrally connectedby horizontal bars 16 which aid in properly positioning the nut membersand reinforce the base block. Otherwise, the forms of Figures 4 and 5are the same as the form of Figure 1.

Minor changesmay be made without departing from the spirit and scope ofthe in -vention as claimed.

What I claim as new is:

1. A chimney cap comprising a molded concrete baseblock having a fluepassage and providedy with upright corner posts, a hood mounted on theupper ends of the corner posts, said hood embod ing a-metallic platehaving an upwardly arclied intermediate portion an'dinclined ends andpairs of nuts threaded on the upper ends of the corner posts betweenwhich the hood is removably clamped, saidcorner posts passing throughthe hood at the juncture of the inclined ends of the hood with thearched intermediate portion thereof. y

2( A chimney cap of the class described comprising a precast concretebase block of truncated pyramidical configuration having a flue passage,a metallic frame embedded centrally in said block and provided at itscorners with screw-threaded holes.r said concrete block having verticalbores in alineinent with said screw-threaded holes, a plurality elfbetween the down-bent ends and the longitudinally bowed central portionbeing' provided with openings through which the upper screw-threadedends of said rods project` said clamping nuts engaging opposite sidesof' said plate and securing the latter on the upper ends of the rod.

In testimony whereof I ailix my signa ture JOHN J. MATLEVISII.
